摘要
3G视频会议系统由于受到无线网络开放性的限制,难以满足行业客户的特殊安全需求。现有3G视频会议系统的加密存在着诸多技术困难,其一就是常规加密算法对硬件要求高,时延较大。ECC加密算法可以较好地适应3G视频终端设备的要求,是一种可行的加密算法。针对此应用对ECC算法做进一步的优化能更好地适应3G视频会议系统终端的需求。文章提出了一种基于ECC的快速算法,经证明可以有效降低资源需求,提高速度,达到应用要求。
3G video conferencing system, due to its restrictions by open wireless networks, is difficult to meet the specific security requirement of the industry customers. The existing 3G video conferencing systems have many technical difficulties in encryption, one of which is high hardware requirement by conventional encryption algorithm, and large latency. ECC encryption algorithm wit a better adaptability to the requirements of 3G video terminal equipment is an applicable encryption algorithm. Based on this application, the ECC algorithm is further optimized, and thus could better adapt to the requirement of 3G video conferencing terminal. This paper proposes a fast algorithm based on ECC, which is proven to he effective in reducing resource requirement, raising operation speed, and thus up to the application requirement.
